1. VENTILATION & EXHAUST used for

 

Exhaust of toxic waste air
paint vapours, alcohol vapours , glues & adhesives vapours, combustion vapours, chemical toxic corrosive vapours dejection emissions, smoke, auto emissions etc.

Exhaust of the air wasted with small particles
dust, ash, rubber powder, plastic powder, cemment powder, wood powder, paper powder, flour, detergents, washing powder, mines stone powder, carbon powder, medical powder etc

Exhaust of the heating gases
hot air, combustion gases, hot gases etc

 

2. PASSIVE NOISE REDUCTION DEVICES used for

 

Industrial high pressure escapes used to reduce noise of an air and steam pressure comming out from pressure tanks,

High pressure jet in order to reduce the noise level

Combustion engine in order to reduce the noise level, but having a good amelioration of the output power of the engine

 

3. VACUUM CLEANER & ASPIRATOR used for

 

Rising and loading-unloading agricultural seeds

Vacuum systems for dust, sand & gravel, leafs and snow from parks and walking roads.

 

 

 

COANDA EJECTOR named also as "Coanda Nozzle"

Flag Counter

 

They represent fluid devices realised for the first time by Henri Coanda, the inventor of the first jet aircraft of the world, back in 1910.
Coanda Nozzles are fluidic transformers, like electrical transformers, that are supplied by a high pressure & lower primary flow fan, blower or compressor in order to get low pressure & high secondary flow.
Coanda nozzle are capable to increase the primary flow to 1,5-5-20-100 times, depends of the design.
Geometry of the Coanda nozzle are various, having diameter from 20mm to 1-2 m or even more of about 10m in special situations.
The lenght of the Coanda nozzle may be from 150mm, 1m to 10-20m or even 120m in special situations.
The flow are about 10-100-1000 m3/h for normal ejectors and up to 1000000 m3/h for huge ejectors.

 

 

HOW IT WORKS?

CASA MEMORIALA COANDA

 

COANDA EJECTOR = COANDA NOZZLE

The primary flow, supplied the nozzle slot by a fan, blower, compressor or a steam tank, is attached on a Coanda divergent wall creating a huge 90% vacuum over a very small surface.
This lower pressure represent the source of a secondary flow that intakes the Coanda nozzle without any mechanical moving parts as propeller, fan, blower or other rotational or vibrational blade devices

Coanda nozzles are capable to move huge quantity of air having NO MECHANICAL MOVING PARTS using Coanda effect.
